dojox.mvc API suggestions

Description

We have received the following dojox.mvc API suggestions.
Change attach() -> transform(), there seems to be agreement on this change.
Another suggestion was to change direct() to setDirection().
Which I also think makes sense.

Well I got feedback not liking setDirection(), so I will change it to .direction(), and I will change the property being used in at and sync to be bindDirection.
So now would change to: <input id="totalHousing" data-dojo-type="dijit.form.NumberTextBox??"
